s GnoUNn-ENeAGrNG nnrvnwnnnr..

To all whom it may concern f Be it known that I CHARLES J. Bmrr, a

States, residing at Willington, in the county `0f McCormick and State of South Carolina, have invented new and useful Improvements in Ground-Engaging Drive-Whe`els, of

ne object of m present invention is the provlsion of an a vantageousl constructed ground-en aging drivewheel, esigned more articular though not necessarily,for emodiment in the 'subject of my application 1918, Serial Number 228,709.

Another object of the invention is the provision of a peculiar and advantageous ined April 15,

y mounting for the wheel.

t wardly.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof;

Figure l is a vertical section, with the lglears 31 and the pinion 32 in edge elevation lustrating my novel ground-engaging drive wheel and the manner in which the same is mounted between frame bars.

Fi 2 is a section taken in the plane indicate by the line 2-2 of Fig. 1, looking out- Fig 3 is a detail plan illustrative of the pecu lar tread of my novel wheel.

Similar numerals of reference designate corresponding parts in all of the views of the drawings. v

Among other elements the construction i illustrated includes sleeves 22.

Connected securely with the flange 24 at the inner end of each sleeve 22, is a frame 29 here shown. The frames 29 afford bearings for a plurality of shafts 30. Each shaft 30 supports a gearl wheel 31, each of said gear Wheels being in mesh with a pinion 32 fixed En. the axle 27, and each of said gear wheels ein Whee 33 which is comprised in the casing of the wheel, as hereinafter set forth. It follows that when the axle 27 is rotated by power received from the motor through the spur gears 28 fixed on the axle, motion will be transmitted through the gears 32 and 31 to the internal gear 33, thereby causing rotation of the Wheel. The axle 27 is shown as bein providedwith ,fly wheels 0r balance Avc'hee s 35, the same being located adjacent which the following the traction engine constituting also in mesh with an internal gear` Specification of Letters Patent. `Pattnted Sept. 13, 1921.

to the frames 29. Anti-friction rollers 36 are interposed between the axle 27 and the are interposed 2l of the wheel through which the sleeves extend. At 15 are the side members of the frame of a traction engine or the like, and at 16 are nuts threaded on the axle 27, and bearing against the outer sides of the frame members 15.

In addition to the internal gear 33 and the hub portions 21, the ground-engaging drivin wheel comprises casing sections 17, bolted at 18 to flanges on the hub portions 21, and having peripheral portions 19 on which are outwardly directed flanges 20. The said sections 17 are preferably of sheet steel, and the flanges 2 0 are arranged at opposite sides of and are securely connected through the medium of transverse bolts 50 to the internal ear 33. It will thus be apparent that tige gear 33 and the sections 17 each carries the other, and that they are connected together rigidly in a strong and durable manner. It will also be apparent that the flanges 20 and the gear 33 form an eilicient circumferential tread portion that may be depended upon to sink into the ground and adequately prevent lateral delection of the Wheel.

By com arison of Figs. 1 and 3, it will be noted t at the tread portions 19 of the Wheel are provided with Webs 51 arranged transversely of the tread, at opposite sides of the projecting tread portion and in staggered relation. These webs 51 are adapted to bite into the ground and thereby contribute to the tractive capacity of the wheel.

Arranged at inner sides of the frame bars 15 are yoke members 52 in which are supported the outer ends of the sleeves 22. The said yoke members 52 are connected at 53 to the frame bars 15, and are also connected together through the medium of bolts 54 and nuts 55 on said bolts, as clearly appears in Fig. 2. After the axle 27 is withdrawn endwise and the lower yoke members 52 of t e airs are disconnected from the upper mem ers and from the frame bars 15, the Wheel ma be dropped, and when the axle 27 is with rawn endwise and the up er members 52 are disconnected from t e lower members and from the frame bars 15, the

Wheel may be raised. Again by withdrawing the axle 27 and disconnecting all of the yoke members 52 the Wheel may be eXpeditiously and easily removed from the :tra-me.

, It Will also be observed that the outer end portions ofthe sleeves 22 are of such a diameter that they are capable of being moved endvvise through the hub portions 21 of the Wheel. Y v

Having described my invention, what I claim and desire to. secure by Letters-Patent, is:

l. In a ground-engaging drive wheel, the

combination. of hub portions, a vertical y central annular member, and casing sections joined to the hub portions and having in- Wardly directed tread portions and 'out- Wardly directed flanges thereon opposed to and connected with the annular member.

2. In a ground-engaging drive Wheel, the combination of a longitudinal central annular member, and casing sections each having inwardly directed tread portions cone nected to the annular member.

3. A groundengaging drive Wheel comprising an annular member having internal gear teeth, hub portions, and casing sections joined to the hub portions and having inwardly directed tread portions on which are flanges joined to the annular member.

4C. The combination of spaced frame bars, sleeves arranged with their outer. ends in opposed relation to theinner sides oi said j bars, an axle extending through the bars and CHARLES Josnrn Bnrri.
